Thaneos was satisfied. Hadria prospered, and his faith was now omnipresent. He was strong - the strongest of the gods on this world, no less. Vanida was now part of a pantheon with him, of course, but he had grown more tolerant over the years... And Az-Sho had incurred his fury before, which had convinced him to leave her be, if only to spite him. He was at the height of his powers, and nothing indicated his strength would stop growing. The times were good.
And so, on that day, he made a choice. He would no longer be the Wanderer. Of all the deities of this universe, he was the mightiest - and he had not even been born from the overgod who had created this place. He was Mighty, and from now on, all mortals would know him as such. He focused an immense amount of powers towards that sole thing, strength; and, when it was over, the Wanderer was no more; the Ancient of Might had been born.
Now, he needed an army. An army to guard his fortress if war ever came to Eversummer. Many warriors lived in Hadria - the mightiest army of the world, in fact, but those would not be enough. Over the years, thousands upon thousands of fighters had died within the empire; and amongst those, he chose the best of the best. The ten thousand best soldiers to ever have died while they believed in his power were brought from the dead, to man the walls of his Halls for all of eternity. If new, better warriors died after the foundation of this legion, they would replace the worst of those already in guard. The army manning the Halls would be the mightiest of all time.
His plans, however, were interrupted when he felt something terrible. Tens of thousands of souls died within one instant. In one mighty blow, a god had all but wiped out an entire race. This would not do. He knew who had done this genocide. And he felt anger.
Thaneos gains a sphere in Might, becoming Ancient of Might. One Mighty Act.
He spends a Death Act to resurrect the best ten thousand warriors to have ever fallen amongst his followers. These warriors will man the walls of his fortress for all of eternity. If a warrior who believed in Thaneos dies, and he is better than one or some of those guarding the fortress, he will replace the worst one. As such, the Dead Legion will only grow stronger over time.
He attacks Az-Sho with the intent to kill him, as retribution for having wiped out the dwarves and having assaulted a nation in Eversummer, despite the Ancient's instructions not to do so. He also teleports Udil into the fight (one act if necessary).
